Modified roots.

• Prop roots (corn) are adventitious, growing from above-ground stems to provide support.

• Storage roots (beet) store carbohydrates.

• Aerial roots (strangler fig) allow a plant to germinate on a tall object, then send adventitious roots to the soil.

• Buttress roots (ceiba tree) are also adventitious; providing support via thick buttresses.

• Pneumatophores (mangroves) project above the water to obtain oxygen in waterlogged soil of swamps.
